My wife has noticed that her severe COVID patients all have vitamin-D levels in the single digits. YMMV.

The only relevant math I need is that humans have done fine with animal fats for thousands of years. The value I need is what I can get naturally. And BTW, I have dark skin, I live in one of the Northest parts of the world humans live, haven't taken vitamin D supplements in years and my vitamin D levels have been great (upper middle of whatever acceptable range they use) when I got tested several times over the past…
> The only relevant math I need is that humans have done fine with animal fats for thousands of years. That's true, however, humans have been spending days mostly inside, both living and working, for much, much less time than that, which dramatically affects how much natural D they are getting from the sun. I'd love to see some research on the overall exposure to sunlight, on average, a person has received over the l…
Again, nutrition science is very misleading.
Sunlight doesn't have vitamins. What supposedly happens is that when you get exposed to sunlight, some of the cholesterol in your blood gets converted to Vitamin D. What part of sunlight, you might wonder. Is it the visible spectrum? No, it's infrared, you know the thing that you get from your radiator.
So, two factors determine how much vitamin D you're going to get:
- cholesterol levels in your blood
- how much heat you're exposed to (i.e. how warm your room is)
I'm sure we need sunlight for other things... like our sleep cycles or whatever... but we definitely don't need it for vitamin D.

No, it's ultraviolet. The opposite side.

To be fair, that's not cheap for Romania. Most people can afford it, yes, but that doesn't mean it's cheap.
Agreed, it's not very cheap for Romania, but the ratio between salaries and blood test prices is better than in other Western countries, assuming prices have not changed significantly in the past few years.
I don't know if the ratio is better. In Spain wages are way higher and blood tests are free. And after reading some comments here it doesn't look that expensive in other countries compared to their median wages.
I know Romania pretty well and I'd say they have Romanian wages and European prices on almost everything.

Another commenter pointed out the factual error about vitamin D coming from IR vs. UV, but there’s another misconception in this post.
The amount of IR you get exposed to is not the same thing as how warm your room is. If you touch a hot pan, or get hot because you’re hanging out where the air temperature is high, that heat isn’t being transferred to you by IR. It’s being transferred by thermal conduction: https://en.m.wikipedia.org/wiki/Thermal_conduction
So even if vitamin D was created by IR, you wouldn’t get any from sitting in a hot room.

Well I mean, in Australia, that leads to skin cancer, so I'll just take some tablets thanks!
We're starting to get into some pretty controversial territory here, but I think you're probably better off still getting at least SOME sunshine. It's speculative, but I believe the skin cancer risk can be dramatically reduced by making sure you're not getting too much linoleic acid in your diet (note: you really have to try at this, tho -- almost every1 is!). Here's a study in mice: https://onlinelibrary.wiley.com/d…
Interesting. Other information [0] suggest that I should consume more lineolic acids compared to other fats to help my risk of Heart Disease that runs in the family. Not looking good for me hey!

You can get an extensive screening for around 120 here in Amsterdam. Probably more expensive if I go through official doctor and have to pay it with eigen risico (first few 100 euros of healthcare you pay yourself).
Where is that? I only looked online, I haven't found anything online that cheap that includes vitamin/mineral levels + hormones.
Did it at https://www.yourlabs.nl/, current price is 189. But you are right, hormones is a seperate test

Can you share the location please? Very interested
